SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 234,910, dated November30, 1880.

Application filed August 13, 1880. (ModeL) To all whom it may concern.-

Be it known that I, WELLINGTON P. DoL- LQFF, of Providence, in thecounty of Providence and State of Rhode Island, have invented anImprovement in Separable Buttons,

of which the following is a specification.

My invention relates to that class of separable buttons where thespring-catches are operated by means of sliding pushers; and it contosists in the peculiar construction and arrangement of the severalparts,whereby the springs are made to have a soft, yielding action withproperly-guided separate pushers, and with a skeleton back, whereby themechanism of the catch movement is exposed to view from the back of thebutton, which is a desirable selling point.

Figure 1 represents a back view of the front portion of the button. Fig.2 represents the same with the skeleton-plate removed. Fig. 3 representsa central section taken in the line of the axis of the post. Fig. 4represents a plan view of the plate to which the fixed post and theposts for holding the springs are at- 2 5 tached. Fig. 5 represents anelevation of the same. Fig. 6 represents a plan view of the pusher. Fig.7 represents a plan view of the skeleton-plate.

In the accompanying drawings, A is the 0 front plate of the button, madewith a turned rim, to. B is a separate plate, to which the springs,pushers, and fixed post are attached. 0 is a skeleton-plate, whichserves to retain the springs in place and to expose to view the workingparts of the button. D is the hollow post, which is attached to the shoeE.

F F are the pushers, stamped out with an open notch, j, at their rearends to receive the turned -down ends 9 g of the springs G G,

. 4.0 which are coiled at 9 around the spring-holding posts H H attachedto the plate B, the arm 9 of the spring resting against the inner sideof the rim a.

The lips b I), turned up from the edge of the plate B, serve to hold therear endot' the pushers F F and prevent them from rising from the faceof the plate, and they are also guided by the fixed post I, which isattached to the center of the plate B, between the adjacent edges of thepushers F F.

The plate B is soldered to the back of the plate A, and the plate (3,provided with the holes 0 c, which are placed over the ends of thespring-holdin g posts H H and secured thereby, prevents the springs fromrising 1 when under the action of the annular catch at of the hollowpost.

The rim a is slotted circumferentially at opposite points to receive theends f"]" of the pushers F. Y

The long arm of the springs G G serves to clasp the catch (1 upon thehollow post D.

I claim as my invention- In a separable button, the combination of thefrontplate, A, provided with aperforated 6 5 rim, or, and the plate B,provided with the fixed post I, for guiding and supporting the hollowpost D, the spring-supporting posts H H, and the turned lips I) I), withthe pushers F F, provided with the open notches f, springs G G, formedwith a downward turn, g, a coil,

g, and an arm, 9 resting against the inner side of the rim a, and theback 0, provided with the holes 0 0, for attachment to the posts H H,all arranged and operating substantially as described.
